ONCIDIUM PHALAENOPSIS. Native of Ecuador. 
A variety of O. cucullatum, which see. 
ONCIDIUM ROGERSII. 
A variety of O. varicosum (q.v). 
ONCIDIUM SARCODES. Native of Brazil. 
A showy species with long tapering pseudobulbs, each about 5 inches tall, dark 
green in colour with a pair of leathery, shining green leaves up to 9 inches long 
by 2 inches broad. The flower spike is from 2 to 5 feet long, branched and many- 
flowered, with blossoms up to 2 inches in diameter. Upper sepal roundish, yellow 
with dull brown cross-bars, the lateral ones lance-shaped and dull brown coloured. 
Petals tongue-shaped and pointed, two-thirds from the base, bright brown spar- 
ingly lined with yellow, top portion yellow. Broad undulated lip, clear yellow 
except for a few red spots at the base. Flowers in Spring and lasts very well. 
Treatment as for O. cornigerum. 
ONCIDIUM SERRATUM. Native of Peru. 
A good species with large, oval pseudobulbs bearing long, broad, leathery, bright 
green leaves. Flower scapes up to 12 feet long, twining and branched, and carry- 
ing many good-sized flowers, often exceeding 3 inches in width, with wavy edged 
sepals and petals. The upper sepal is fiddle-shaped, while the laterals are oblong 
and curving. Petals oblong and curved in towards the column. They are bright 
chocolate brown, the edges being bright yellow. Lip, small and spear-shaped, is 
bright yellow and has a prominently ridged crest. Flowers in Winter and lasts 
a long time. Culture as for O. cornigerum. 
ONCIDIUM SPACELATUM. Native of Mexico and Guatemala. 
A popular and hardy species. Pseudobulbs elongate, ovate, flattened, two-edged, 
with long, sword-shaped leaves. Flowers spikes up to 5 or 6 feet long and branched, 
crowded with attractive flowers, in the variety majus, about 13 inches across, 
and in minus, about 3 inch in width. Sepals and petals bright yellow barred with 
deep chestnut brown. The lip is roundish in front and narrowed at the base. It 
is yellow, the contracted part being barred with brown. Flowers in early Summer 
and lasts three to four weeks. I find that this species grows well in Brisbane sus- 
pended from the branch of a tree which protects it from the too-direct rays of 
the sun. Copious water in Summer and less in Winter, but the compost never 
allowed to become dry. Ordinary bushhouse treatment will serve it quite well 
from Sydney northwards, though in the south it is well to get it under glass in 
the coldest weeks of the Winter. 
ONCIDIUM SPLENDIDUM. Native of Guatemala. 
One of the finest species with roundish, compressed pseudobulbs with a single 
thick, leathery, oblong-ovate leaf about 8 inches long and 2} inches wide. The
